This is one of a number of selective enrichment broths that can be used in the isolation of Campylobacter spp from clinical, food and environmental specimens and contains nutrients to aid in the resuscitation of damaged organisms. The medium is enriched with Lysed Horse Blood and made selective by the inclusion of Vancomycin, Cefoperazone, Trimethoprim and Amphotericin B. Following incubation at 37ºC the broth is usually sub-cultured onto an appropriate solid Campylobacter medium.
